STMicroelectronics STA016A

DESCRIPTION

The STA016A is a single chip MPEG 1, 2 and 2.5 Layer III audio decoder with embedded CDROM decoding capability. It can be easily connected to most existing CDDSP devices via a software configurable serial link. A tipical application block diagram is show in Figure 1. The audio sources, for instance could be an external flash memory.
